KVM (Keyboard Video Mouse)

Have made a few posts talking about the mini PC I ordered a, Minisforum UM580.   That ships some time near the end of the month (September 2022).  In the mean time was looking into a way to add to my current computer desk setup.  Came across devices called KVM (Keyboard Video Mouse).  These things let you use one with a bunch of computes.  There are really fancy ones with a big price tag that can run up to four computers.  I don’t need anything that nice.  Took a look at few on Amazon.ca.  All most went this a USB 3.0 $750.00 one.  Then I seen this one > here.   It had lots of ratings.  Plus at the time of typing this (September 16, 2022) they had it for %15 off.  So saved on the tax and it had free shipping.  Should have it in my hands next week.
